Can I capture scene depth to a render target?

sorry for hijacking the thread (I’ll take advantage of the fact that mr. Ketchum is answering!)

now that I’ve setup the capturing I cannot manage to get a proper view.

like I said before, what I want is a top-down heightmap of my scene. the problem now is I have a depth precision vs. FoV tradeoff. the more FOV the more distorted the scene is (as opposed to being top-down), but the less FOV the less Z-precision I get.

using a FoV of 26.0 this is what I get (already some FoV distortion and horrible depth precision)

is there a way I can set up a near and far plane? or some other workaround?

thanks
